The BTB747 is a seven string BTB series solid body electric bass model introduced by Ibanez in mid 2017. It is made in Indonesia and was initially part of the Ibanez Bass Workshop line; since 2018 it has been in the standard line.
The BTB747 features neck through body construction with a walnut top and mahogany back on ash wings attached to a nine-piece maple, rosewood and walnut neck with a 24-fret rosewood fingerboard with abalone dot position markers. The body has a double cutaway design with very distinctive, narrow, curving horns. Components include a pair of Bartolini BH2 passive pickups with an Ibanez custom preamp with a three-band EQ, stainless steel frets including a zero fret, a Mono-rail bridge with 15.5mm string spacing, a locking Neutrik stereo output jack, a plastic nut and Ibanez tuning machines.
For 2018 the rosewood fretboard was replaced with jatoba and the maple, rosewood and walnut neck was replaced with a maple, panga panga and walnut construction. For 2019 the mahogany back was replaced with okoume.
